If you have the original battery Reserve Capacity specs it is an acceptable 
quick test
to see if the battery is good but maybe worn or at end of life.

If possible test the battery(s) individually, Charge fully, bring battery to 
around 80F and
time how long it will sustain a 25 amp load before reaching 10.5v. Note that 
takes the
battery to almost complete discharge and may significantly shorten it's life. 
If the voltage
gets to 11.0v and the time is less than half the RC spec there is not much to 
be gained
testing further, the battery is worn out.

The 10.5v sounds pretty bad but that is an under load voltage and is different 
from an
at rest voltage.
